Biopharmaceutical Industry

The medical industry has extremely strict requirements on the quality of compressed air, and the selection of air compressors must meet medical safety standards and special application requirements. The selection of medical air compressors must meet the core certification standard ISO 8573-1 Class 0 (oil-free certification), with an oil content of ≤0.001mg/m³ (10 times higher than the industrial standard). Oil-free scroll machines/oil-free screw machines are the best choice.

PET Bottle Blowing Industry

In the PET bottle blowing industry, the air compressor is the core power equipment, which directly affects the quality of preform molding, production efficiency and energy consumption cost. The air compressor in the PET bottle blowing industry needs high cleanliness (oil-free), must reach ISO 8573-1 Class 0 (oil content ≤ 0.01mg/m³), high-pressure stable air supply, bottle blowing pressure usually requires 25-40bar, low-pressure delivery requires 6-10bar, and pressure fluctuations must be controlled within ±0.2bar, otherwise the bottle wall thickness will be uneven. Dry air to prevent condensed water from affecting mold temperature control, and large flow continuous air supply is required.
